Introduction

This tutorial is designed to help you configure Cassandra Cluster on DigitalOcean instances. I will walk you through the process of installing Cassandra on one node and show you how to configure other nodes, so we can create a cluster.

Before we start go ahead and create droplets yourself. For my configuration I have chosen Ubuntu 14.04 on a $20 a month VPS and selected London as my region.

How does it work?

Simply copy and paste the http:// link you want to use. The tool will create a javascript code which you can then copy to a .js file or inside the html template ( usually in the < head > section ).

Once executed the code will create an img tag with some inline style = > style=”width:1px;height:1px;display:none;”. The user will not see the image, but the browser will make a request to the desired domain.
